Irsay also owns a trio of guitars once strummed by Paul McCartney, the late George Harrison and the late John Lennon, prompting the Colts figurehead to tell the media: "Finally, after 45 years, the Beatles are together again."

More than just a music lover, Irsay previously made waves in the literary community by paying $2.43 million in 2001 for Jack Kerouac's original "On the Road" manuscript, an epic banged out feverishly by the writer on one long and winding -- and now yellowing -- scroll.

That's nearly $5 million for a book and a musical instrument, which looks interesting next to the measly $2 million that Matt Hasselbeck will make for his autumn heroics in 2015.
